' CONNECTOR F03 ELECTRIC CIRCUITS.

, tric Circuits; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en.- able others skilled in the art to which 1t ap:

- pertains to make and use the same. 7

My invention relates to connectors for electric circuits, and is ,more particularly adapted to be used where such connectors are subjected to vibrations and other causes and forces tending to loosen them. I mm to produce a connector which cannot be shaken loose, which locks its fastening means and which is easily and economically manufactured.

These and other objects of my invention,

its uses and the invention-itself'will be better understood from a description of an embodiment of the invention. 7 I

Figure 1 is an elevation of an automobile horn with one corner cut away and sectioned to show an elevation of .an embodiment of vation of the embodiment of my invention shown in Figs. 1 and 2 associated-with a fastening means for the same.

Fig. 4 isa perspective of the embodiment shown in Figs. 1, 2 and 3. 4

Referring now to the drawings and to the embodiment of my invention shown. therein, at 5 is shown the main or body portion of a connector embodying my mvention, which is provided with an elongated slot or opening 6 extending down the middle part of the body portion and being open at one end 7. At the other end of the body portion there is connected to such body portion a terminal arm 8 provided with a mouth 9 for a purpose to be described. In the device illustrated' in the drawing this arm extends at an angle of about. 45 to the main portion 5, thereby raising the free end of the arm above the base .20.. The terminal is provided with convenient means for attach- I Specification 0t Letters Patent.

ing it to the base, here shown as a wing 10 on one side of the body portion and turned downward at an angle of substantially 90. to the body portion. "A catch 11 is connected to the other side of the body portion and extends upward therefrom orin an opposite direction from the wing 10. The main portion 12 of the catch is at substantially 90 to the body portion 5. The upper part of the catch is turned over to form an arm 13 extending therefrom substantially parallel to the bodyv portion and toward the body portion.. This arm terminates in a lip 14 which extends downwardly about midway the slot 6.

The parts are preferably made integral and when made integral, the whole device may be stamped out in the shape of a flat blank and bent to form the terminal, by'a few operations.

The function of the .various parts will be thoroughly understood from a description of the use of the invention, such as occurs in connection with automobile horns, one of which is illustrated in Figs. 1 and, 2 employ ng inventions made according to my in vention.

Referring now to Figs. 1 and 2, at 20 is shown a base for the connectors and at 21 are shown bolts employed to connect the parts of the horn together and'to' furnish a conductor for the electric current from the exterior to the interior of the horn. The

.bolts are driven through the openings indicated in the parts of the horn in Fig. 1 and the nut 22 is screwed part way down. The connectors are then 'sli ped under the heads of the bolts, the shan of the bolt passing through the opening 7 as the connector is slid along the base 20 into the back end 25 of the slot where it rests when the connector is in use, the terminal arm 8 projecting outward and upward, as indicated in Fig. 2. The lip 14 is slipped into the slot 26 in the head of the bolt or screw, locking the same and preventing its further rotation.

When the connector is placed in position, the wing 10 is slipped along one side of the base piece 20, preventing the rotation of either the connector or the base 20. The nut 22 is then screwed down tightly, drawing the lip 14. into the slot 26 and locking the parts together. The conductor on the outside of the horn is then fastened to the shank 1f the bolt between the nuts 29' and as j 30. The conductors 31 within the horn are connected in the terminal arms 8, as illustrated in Fig. 2. In the embodiment illustrated the ends of the conductors 81 are connected in the mouths 9 of these arms.

I have shown this embodiment of my invention and these details for the purpose of describing the invention. 1 do not wish to be limited either to this particular form or these particular details, as it will be apparent that many departures may be made from the same without departing from the spirit of the invention.

I claim p 1. In a connector for electric circuits, the combination of a main portion provided with an opening for the shank of a screw or bolt, a base engaging wing on one side of said body portion, a terminal arm on one end of said body portion and a screw or bolt locking catch on the other side of said body portion provided with a lip to enter the screw head slot and hold the same against rotation.

2, In a connector for electric circuits, the combination of a main portion provided with an opening for the shank of a screw or bolt, means to engage the connector supporting base to prevent relative movement there between, a terminal arm on said main portion and a screw locking arm on said main portion provided with a lip for entering the slot in the screw head engaging the walls thereoi and preventing rotation of such.

screw.

3. In a connector for electric circuits, the combination of an integral 0' inector having a base locking menfier, son locl member and a terini arm all integral with. a main or body pc 4. In a connector ior electric circuits, the combination. with a fiat body portion provided with a slot open at one end of said body portion for the entry of the shank of a bolt or screw to be retained in said shank, a terminal arm integral with said body portion connected to the other end thereof, a base engaging wing integral with said body portion and extending downward from one ter aces side thereof and a locking arm integral with the base portion extending upward from the other side of the body portion and provided with a downwardly turned lip for entering the slot in the head of the screw or bolt retained in said slot, said lip when in position engaging the side walls of said slot and locking said screw or bolt against rotation.

5. in a connector for electric circuits, the combination of a body portion provided with an opening for a screw or bolt shank, a terminal arm on one end of said body portion, a base engaging member on one side of said body portion for engaging the connector base and preventing relative movement of said base and connector, and a screw locking arm on the other side of said body portion provided with a lip for entering a slot in the head of a bolt or screw.

6. in a connector for electric circuits, the combination of a body portion, means through which the her y portion is connected 'to-a base, means to prevent relative movement between the base and connector and means on said body portion to lock said connecting means against movement.

7. in a connector for electric circuits, the combination of a body portion, means including a device with a slotted head through which said connector is fastened to supporting base, and apparatus mounted on said connector to engage the slot in the slotted head of said device to prevent rotation thereof with respect to said connector.

8. in a connector for electric circuits, the combination of a body portion, means including a device with a slotted head to fasten said connector to a supporting base, a wing on said connector to engage said base and lock the connector with respect thereto and an arm provided with a slot entering lip for locking said device through the slot in the head thereof.
